SPECIFICATION forming part of Letters Patent No. 410,423, dated September 3, 1889. Application filed April 20, 1889. Serial No. 307,950. (No model.)

To @ZZ whoml it may concern:

Beitknown that I, EDMUND LUNKENHEIMER, a citizen of the United States, residingat Cin- -einnati, in the county of Hamilton and State of Ohio, have invented certain new and useful improvements in Grease-(inps, of which the followingis a full, clear, and exact description, reference being had to the accom panyingd rawngs, forming part of this specification.

My invention relates to grease-clips for lubricatingjournals and bearings; and it has for its object the improved construction of such cups, whereby the packing may be expanded to prevent leakage.

The novelty ot' my invention will be herewith set forth, and specifically pointed out in the claim.

In the accompanying drawings, Figure l is a central sectional elevation otA my improved cup under one form of construction. Fig. 2 is a corresponding view under another form of construction.

The same letters of reference are used to indicate identical parts in both the figures.

The metal base or standard A of the cup has a central bore aV extending through it for the escape of the lubricant from the cup to the bearing or part to be lubricated, and it has its lower end eXteriorly threaded, as at b, as ameans of attaching it to the bearing or part to be lubricated. lt has at its upper-end a disk c, exteriorly threaded to be screwed into the interiorly -threaded metal cup B, which is a cylinder closed at its upper end, but open at its lower end to receive the disk c. That portion of the standard A just beneath the disk c is also exteriorly threaded, as at d, and receives upon this threaded portion the packing-ring e, of any suitable compressble material--as leather, for instance-Which is conned between the under side of the disk c and the upper side of a washer C, which is fitted around the threaded portion d and :is held and forced upward, as in Fig. l, by a and bearing against thc under sin@ n? the.

washer, or, as in Fig. 2, by securing une washe.` directly upon the threaded portion land providing its under side with turning or Spanner lugsf. The washer (E is ot' just suilicientd- 5o arneter to snugly fit within the cup i3 without coming in Contact with the threads of said cup, and its upper side is made convex or beveled, as shown, so that by forcing it up the packing is pressed outward from the cen- 55 i surfaces against the packing convex or bev- 65 eled,as will be readily umlerstood. he uuder side of the disk c is roughened or provided with holding or retaining points, as seen at h, to engage with and prevent the turning of the packing while compressing it 7o by the adjustment of the washer. The feeding of the lubricant is` accomplished by screwing down the cup B upon the disk c.

Having thus fully described my invention, I claim- 75 The grease-cu p herein described, consisting, essentially, of the interiorly-thrcaded cup B, the hollow standard or stem A, having the exteiiorly-threaded disk c, the expansible packing e, and the adjustable screw-connected 8o washer O, for forcing the' expansible packing outward into the threads of the cup B, whereby'to enable the screw-joint between the cup and the standard-disk to be kept tight withoutdisturbing the relative positions of said 85 parts and without disconnecting the cup asa whole, substantially as described.

EDMUND lLUNKENHEIMER.
